Things that go fast and explode

autopope's main blog points to Encyclopaedia Astronautica's history of Project Dynasoar.

A fascinating piece on the military implications of a skip-glide orbital vehicle - along with the liquid flourine/hydrazine rockets that could have been used to launch it. Imagine the down-range effects of a trail of hydrofluric acid...

Probably nothing significant as it would be very high up and disperse widely (probably knackering lots of ozone in the process).

Someone pointed out at Novacon that most of the current spaceplane projects will fall foul of various treaties that were framed primarily to stop things like DynaSoar.

Incidentally, Charlie's main blog

Who or what ...
... is NetSweeper?

I can feel a snotty letter and, if necessary, a Writ alleging defamation, coming on.

It appears to be this:


Censorware for schools and the like...

Re: Who or what ...
They're crap, basically. On the default setting (I think) which is used by the London Grid for Learning their censorware does things like blocking a Google search for "chemical analysis" because of the first four letters of the second word. They block hundreds of biology-related sites as "sex sites", chemistry and physics sites as "criminal sites", Buffy fanfic sites as "occult sites". My web site was blocked as an "on-line gaming site" until I complained, and I'm far from alone. You may have noticed some discussion of this on rec.arts.sf.fandom recently, it's getting to the point where it seriously hampers research, which is supposed to be part of school coursework these days. It appears to be impossible for a school to be part of the London Grid for Learning (which provides high-speed connections for most of the schools in London) without Netsweeper getting in the way.

Sooner or later someone big is going to sue them, and won't settle for just being whitelisted, which is what they appear to do if challenged. It can't happen too soon for me.

Liquid Flourine? Dear Ghod. Never mind the environmental effects, what about the poor ground crew who would have had to handle the wretched stuff?

Can you say, "workers compensation"?
Oh, man, what a legal nightmare that would have been!

I remember a Dyna-Soar something from when I was about eight - an Airfix, perhaps ? But that was a bathtub sort of lifting-body thing, with little upswept wings.

I wonder what the connection was ?
